[PATCH v4 0/5] usb: musb: da8xx: Add DMA support

[Alexandre Bailon <abailon-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>]

This series update MUSB driver to add DMA support to DA8xx.
It should be applied on top of
"[PATCH v3 0/3] usb: musb: cppi41: Add a way to manage DMA irq" but
"[PATCH v3 0/3] dmaengine: cppi41: Add dma support to da8xx" and
"[PATCH] arm: davinci: Make the usb20 clock available to PM runtime"
are required to make it work.

Changes in v4:
- Update and clarify the commit message of patch 5
- Fix the typo in patch 3

Changes in v3:
- Remove PM runtime callbacks.
  I have update arch/arm/mach-davinci/pm_domain.c to let PM runtime control
  the usb20 clock.
- Only use PM runtime sync operation.

Changes in v2:
- Clock and IRQ management has been moved to MUSB DA8xx glue
  (was in CPPI 4.1 driver)
- I have added a partial support PM runtime. The goal was to use PM
  runtime to manage clock of MUSB and CPPI 4.1 (they use the same clock).
- CPPI 4.1 is now achild of MUSB DA8xx glue.

Alexandre Bailon (5):
  usb: musb: da8xx: Remove CPPI 3.0 quirk and methods
  usb: musb: Use shared irq
  usb: musb: Add support of CPPI 4.1 DMA controller to DA8xx
  usb: musb: musb_cppi41: Workaround DMA stall issue during teardown
  usb: musb: da8xx: Add a primary support of PM runtime
